Abstract: An HVAC controller may be controlled in response to a natural language audio message that is not recognizable by the HVAC controller as a command, where the natural language audio message is translated into a command recognizable by the HVAC controller. The HVAC controller may be a thermostat including a housing that houses a temperature sensor, a microphone, and a controller. The controller may identify a trigger phrase in an audio stream provided by the microphone.
